Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses that the list includes both config-defined and add_related_project-added projects, which is useful behavioral context. However, it does not explicitly state that this is a read-only operation or mention any side effects, errors, or return format. For a simple list tool, this is adequate but not comprehensive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
